SUMMARY

The discussion centers on the placement of an electromotive force (EMF) in a closed circuit experiencing induction due to a time-varying magnetic flux. It is established that the EMF can be represented by a battery placed across the resistance in the circuit, allowing for the calculation of current intensity. In scenarios with multiple circuit elements, each can be analyzed by considering the voltage across its extremes as equal to the EMF. To determine the current through any segment of the loop, one can break the loop and connect a battery representing the EMF at that point.

Suppose we have a closed circuit with a time-varying magnetic flux. An EMF is inducted on the circuit.

Where would we put the battery representing the EMF? For example, suppose we have a resistance in the circuit and we want to know the intensity through it. Would we just set the voltage against its extremes to be equal to the EMF?

If so, would we, in the general case where there are more elements, analyze each one as if there was a voltage between its extremes?

If you want to know just current through the loop, break the loop at any small segment of it and connect the "battery" of the same EMF there.
That would work.
